Key strata of mining-induced seismicity in overburden rocks in coal mines and the energy-releasing mechanism of its fracture [PDF]
Meitan xuebaoMining-induced seismicity in strata has become one of the main dynamic phenomena in some coal mines. The theoretical identification of the main controlling rock stratum where mining-induced seismicity occurs is the basis for accurate prevention and ...

Classification of Mining Induced Seismicity at the Kiirunavaara Mine
, 2022 The risk associated with mining induced seismicity and the related rock bursts has become one of the major threats to the safety and sustainability of mining at the Kiirunavaara mine, Sweden. The mine is owned by LKAB and is using sublevel caving mining method.

Mining induced seismicity in Sweden
, 2004 The virgin stress state in the rock mass is disturbed by mining, which leads to locally increased or decreased stresses. The rock mass in Sweden is generally composed of high strength brittle rock types, so the risk of seismicity and rockbursts (violent failures) increase with increasing depth of mining due to increasing stress levels.

Crowdsensing location method of mining-induced seismicity based on the phone mobile sensor network
工程科学学报, 2022 To improve the positioning accuracy of a mining-induced seismicity monitoring system, reduce the monitoring blind area, and reduce the monitoring cost, based on the distributed idea, this paper proposes a positioning method of mining-induced seismicity ...
